Clogged or slow drains are more than a nuisance—they can lead to backups, odors, and damage. Drain Doctor provides professional drain cleaning in Covina, West Covina, and across the San Gabriel Valley for sinks, tubs, showers, and main lines. We use the right tools for the job, from augers to hydro-jetting, so we clear the blockage effectively and help prevent quick recurrence.
How we help
We diagnose the location and cause of the clog, then choose the best method to clear it. For simple clogs we may use a snake or auger; for tougher blockages or main lines we use hydro-jetting or other professional equipment. We can also run a camera afterward to confirm the line is clear—especially helpful when the same drain keeps slowing down.
